Hello and thank you for choosing Just Answer. My name is ***** ***** I will do my very best to get you the answer you need to your question.
It is very likely that our problem is caused by your solenoid being faulty. If your solenoid is sticking in the closed circuit position, your starter will continue to spin, as long as there is voltage present from your battery positive post, to your solenoid.
Also remove the small wire from your solenoid. Let's see if your starter will continue to spin when you connect your positive cable to your battery, with this wire removed.

If this is not the problem, then you may have a faulty ignition switch.

If your ignition is faulty, your start circuit can remain closed, even when you release your key to run position. This can cause the small wire on your solenoid, to maintain 12 volts, regardless of the position of your ignition switch.
